Down
- 1. possessing an extraordinary power or ability to attract a magnetic personality.
- 2. the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.
- 3. is a measurement of the total magnetic field which passes through a given area.
- 4. demonstrated that electric and magnetic fields travel through space as waves moving at the speed of light.
- 5. Any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be "induced" in the coil.
